SELF-CLOSING HOSE NOZZLE.

Application mea August rz, 1925.` serial No. 50,550.

To all lwhom zt may concern.'

Be it known that I O'rro E`. SzEKnLY, a citizen of the United tates,residing at Moline, in the county of Rock Island and State of Illinois,have invented certain new and useful Improvements in Self-Closing Hose'Nozzles, of which the following'is a specication. This nozzle isintended primarily for use l0 in connection with the dispensing ofgasoline from lling stations, and is of they selfclosing type which iscoming into extenslve use at the present time. In the use of nozzles ofthis type, the valve for controlling the ultimate discharge of thegasoline is located in the nozzle rather than at a point distanttherefrom, so that the flow of asoline is under the immediate control othe operator standing in close proximity to the gasoline tank on the carbeing charged, at

whichA point he can readily observe the inflow of gasoline and cut oil'the su ply when the tank has been filled. In such case the hose to whichthe nozzle is secured remains 2 full in contradistinction to thesO-called dry hose apparatus controlled by a nozzle at theA upper end,lwhchordinarily necessitates the services of two men in order to avoidspilling and waste of gasoline.

80 The nozzle of the present invention is de,- signed to afford an easyand convenient pistol grip for the hand of the opera-tor in conjunctionwith a trigger-like lever for controlling the supply of gasoline, theseparts being so arranged that the supply hose will occupy a natural andconvenient relation to the arm of the operator, thereby enablingV thehose and nozzle to be easily controlled by a single hand.

The invention also relates to the means provided for the prevention of'lost motion in the contact between the lever finger and the valve stem,and to the general `arrangement of the device as a whole.

l5 Further objects and details will appear from the descriptioncontained in the specification in conjunction with the drawing 'wherein-Fi 1 is a' sectional Velevation of the 5.0 no'zzfegm '24 mounted upon aFig. 2 isa top or plan view thereof; and

Fig. 3 is an oHset cross sectional view ta'- ken on line 3--3 of Fig.1,'looking in the direction of the arrows.

The nozzle comprises 'a cylindrical barrel 55 10 provided'near itsforward end on its upper side with a transversely extending protuberance11 which, on its forward side, merges into a half cylindrical boss 12which is closed by a screw plug 13. The rear end 6o of the barrel isprovided with interior threads 14 adapted to engage with the dischargeend of a hose, not shown, and within the barrel, near its rear end is anannular flange lbeveled on its rear edge 16 to afford 65 a seat for avalve 17 which is provided with a plurality of inwardly extendingcircumferentially arranged fingers 18 which serve to center the valve.

The valve is provided with a valve stem 19 entered through atransversely extending bridge plate 20 which furnishes a guide for thestem. The valve stem is surrounded by a coiled spring 21 `which abutsagainst a washer 22, the arrangement being such as to `permit openinglof the valve uponcompression of the spring.

The valve stem is operated by means of a swinging linger 23 dependinfrom va hub uared s aft 25 termi- 80 nating at its inner en in acylindrical journal 26 mounted within a journal recess 2-7 in the endwall of the protuberance 11. The l shaft 25 at its opposite end isentered through a gland 28 adapted tocompress a 85 packing 29 bearingagainst a collar 30 which ts against an inturned flange 31, thearrangement being such as to afford a tight closure against the escapeof gasoline.

The protruding outer end of the shaft 9 carries a trigger-like lever orhandle 32 which extends downwardly and inwardly below the barrel to apoint immediately in advance of ya pistoligrip handle '33 depending fromthe" under side of the barrel. This l arrangement permits the operatorto grasp the pistol grip between the thumb and palm of the handand tograsp the trigger with the fingers, thus opening the valve by aretraction of the fingers. The arrangement is 10 also one which reststhe rear or butt end of the nozzle upon the hand immediately behind thebase of the thumb, with the ,attached hose leading up along the forearmso that the entire nozzle will be conveniently supported and easilymanipulated, and can be readily turned by movement of the Wrist into anyposition desired.

In order to hold the finger 23 into tight engagement with the valvestem, and to prevent lost motion at this oint, the hub 24.- is providedon its forwar side and at right an les to the linger 23 With a lug 34provied on its upper face with a small boss 35 which centers a lightcoiled spring 36, the upper end of which bears againstthe plug 13, sothat a constant tendency of the spring 36 will be to force the finger 23into contact with the valve stem, thereby preventing any lost movementdue to wear or improperadjustment.

The barrel at its forward end is provided WithI interior threads 36 fora coup-ling 37' which carries a spout 38 which may be either rigid orflexible as is desired and of any suitable material, metallic` orotherwise, commonly employed in the construction of spouts intended forlikev purpose. The barrel is also provided on its upper side with anupstanding loop which affords a convenient means for suspending thenozzle.

In use, the nozzle will be engaged and grasped by the hand in the mannerdescribed and manipulated to bring the spout into desired position,after Which the compression of the lingers will effect a retraction ofthe valve stem and an opening of the valve which will remain open untilthe trigger is released. Although the nozzle is intended primarily fordispensing gasoline, it is obvious that it might be employed for otherpurposes in which facility of manipulation and ease of control aredesired.
